Design of a Laboratory Scale Solar Microgrid Cyber-Physical System for Education

Abstract

Renewable energy sources such as solar and wind provide an effective solution for reducing dependency on conventional power generation and increasing the reliability and quality of power systems. Presented in this paper are design and implementation of a laboratory scale solar microgrid cyber-physical system (CPS) with wireless data monitoring as a teaching tool in the engineering technology curriculum. In the system, the solar panel, battery, charge controller, and loads form the physical layer, while the sensors, communication networks, supervisory control and data acquisition systems (SCADA) and control systems form the cyber layer. The physical layer was seamlessly integrated with the cyber layer consisting of control and communication. The objective was to create a robust CPS platform and to use the system to promote interest in and knowledge of renewable energy among university students. Experimental results showed that the maximum power point tracking (MPPT) charge controller provided the loads with power from the solar panel and used additional power to charge the rechargeable battery. Through the system, students learned and mastered key concepts and knowledge of multi-disciplinary areas including data sampling and acquisition, analog to digital conversion, solar power, battery charging, control, embedded systems and software programing. It is a valuable teaching resource for students to study renewable energy in CPS.

Assessment on the Acceptability of the Off-Grid Solar Panel Installation Trainer Board

“…Students learned and mastered key concepts and knowledge in multidisciplinary areas such as data sample size and collection, analog to digital conversion, solar power, battery charging, regulation, embedded systems, and software programming through the system. It is a powerful instructional resource for CPS students studying renewable energy (Guo & Kors, 2021).…”

A laboratory scale IoT-based measuring of the solar photovoltaic parameters

“…The charging process operates at the absorption stage until the battery is almost at the absorption voltage setpoint. At this stage, a constant voltage is applied for 150-180 minutes (depending on the type of battery) so that the battery voltage is at the setpoint [32]. Finally, once the battery is fully charged, the voltage is reduced to a float voltage setpoint so that it can be used to supply the load.…”

“…Perubahan terjadi dikarena perkembangan pengetahuan manusia seperti penggunaan teknologi (Handayani, 2020;Monasterio & Briceño, 2020). Hal ini membuat berbagai lini kehidupan manusia juga mengalami peruabahntermasuk di bidang pendidikan (Abichandani et al, 2019;Guo & Kors, 2021). Penggunaan Teknologi dalam memsupport tercapainya tujuan pembelajran merupakan sebuah hal inovatif dan adaptif (Zahara et al, 2020;Fuchsova & Korenova, 2019).…”
